IMPROVEMENT IN MAGAZINE-GUNS.

Specification formingpart .of Letters Patent No. 128,208, dated J nne25, 1872.

The object of this invention is to improve and simplify that class ofbreech-loading firearms which are used as self-loaders by having amagazine connected therewith, or as a single loader when the operatormay wish or the magazine shall be empty; and it consists in thearrangement and combination of the parts hereinafter set forth anddescribed.

In the accompanying drawing, Figure 1 represents a vertical longitudinalsection of the gun as constructed without the magazine.

Fig. 2 is the same with the addition of the magazine, and showingitsarrangement. Fig. 3 is the breech-block and parts connectedtherewith.Fig. 4 shows the extractor and its connection with the tumbler as usedfor a single loader. Fig. 5 is the breech-block cap or cover. Fig. 6 isthe cartridge-feed regulator. Fig. 7 is the magazine-stop.

Similar letters of reference indicate corresponding parts.

Ais thebed-piece, which contains thebreechblock 0 and supports theoperating mechanism of the gun. The hammer is attached to the tumbler Dby a square socket in the ordinary manner, and operates the breech-blockby the link c' inthe same manner as one of my guns patented September19, 1871. N, Figs. 1 and 4, is the bar of the side extractor, the upperpart operating back of cartridge-flange, the lower part being pivoted tobed-piece A and bent back and upward, and having a notch, 19, whichengages a point, a, of lever 0, said lever being sprung back by thepoint of spring at operating against it near the pivot above. Theextractor is set by pushing back the bar N in inserting the cartridge.When the hammer is carried a little beyond full-cock the rod 1?, beingpivoted to a projection of tumbler D, is carried back until a projectionon the other end of said rod pulls back the lever 0., releasing the barN, by disengaging the point a of lever 0 from notch 19 in back part ofsaid bar, when, if the force of spring m should not be suficient tothrow out the discharged shell, the lever O operates against the bar Nat the point a by the further drawing back of the hammer, thus startingthe shell, which is then thrown out by the recoil of spring m. 0 is thebreech-block, and is hollow at the rear end for allowing the cartridgeto enter from, magazine B, which extends backward through the breech ofgun. S is the breech-block cap, pivoted at the rear end to the top ofbreechblock, and kept in position by small straight spring S. T is thefeed-regulator, pressed forward by small spring T. X is the pusher,pivoted at X to bed-piece A, and is thrown back by force of spring Z,and connected with the trigger Z, by which it is operated, by thetoggle-joint B. The pusher X has also pivoted to it, theother side fromthe toggle B, a bar or dog, B, the upper part of which is pressedoutward by small spring E, which allows of its passing forward under theflange of cartridge by pressing down said spring E.

It will be seen that the upper part of the tumbler D, to which the linki is pivoted, projects above said pivot, the extreme upper end having ascrew or pin connecting the two sides, the upper part of .link i beingbent or out out so as not to prevent the straightening of the joint whenthe hammer is down.

To operate this arm we first turn back the cap S of the breech-block,leaving the mouth of magazine open, into which we insert the cartridges.The back flanges, passing over the first point, push back the rear pointof the feed-regulator T, allowingthem to enter, which, by force ofspring T, returns to its former position and prevents their return.Then, closing the cap S, we may cook the piece and use as a singleloader, only taking precaution not to carry the hammer but little backof the fullcock notch. To insure this the stop g is turned down towardthe back of hammer, where it is retained by the friction-sprin g g. Itis loaded at full-cock by inserting the cartridge forward into thechamber of barrel, and fired by pulling the trigger, which, releasingthe tumbler, allows the hammer to fall, the breech-block, which carriesthe firing-pin f, closing upward, by means of the link i, at the sametime, and

reaching position a little before, or at the time, the hammer strikes.Now, if we desire to use the reserved charges in the magazine, we haveonly to turn back the stop 9, which allows the hammer to be carriedstill further beyond the full-cock, causing the pin L to come in contactwith the feed-regulator T above the pivot in breech-block, on which itturns, causing the rear point to fall and release the flange ofcartridge, which, being sent forward by force of spiral spring of themagazine B, catches on the forward point of the feed-regulator T, whereit is retained until the hammer is let down to the full-cock or nearlyso, when the feed-regulator, being released from contact with pin L,returns to first position by force of spring T. The cartridge is leftfree to spring. forward into the chamber of the barrel by impetusreceived from spiral spring R. The cartridge, in passing from the feed-regulator to the barrel-chamber, forces up the cap S, which thenassists to guide it into the chamber. The

pusher X, working vertically through the breech block, following up,drives the cartridge home, said pusher being operated by the triggerconnected with toggle B, so that when the trigger is straightening thejoint B, by being pulled, it throws the pusher forward, and, driving thecartridge home, the back part of trigger Z reaches set-screw in dog Z.The one motion of pulling trigger pushes the cartridge into thebarrel-chamber and discharges the gum-by releasing dog Z from thetumbler, so causing the hammer to fall and strike firing-pin f as thebreech-block rises to position. When the hammer is again raised afterhaving fired the gun the falling of the breechblock allows the pusher tobe forced back by the spring Z, and the point of dog B engages with theflange of cartridge-shell, when, if the force of spring Z is notsufficient to throw out said shell, by carrying the hammer back beyondfull-cock the breech-block strikes that .part of the jointB that ispivoted to the magazine-tube R has an opening or groove in lowerinterior side, extending its whole length,

and into which a point or screw of the follower R slides freely; but, asit cannot pass the feed-regulator T, prevents it from running out afterthe cartridges have all been delivcred.

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. The spring-bar N, in combination with the lever 0when the latter is pivoted to the bedpiece, and provided with an arm, n,engaging with a notch, p, in a prolongation of the bar N, in the mannerand for the purpose set forth. 2. The breech-block 0 when hinged in therear, and perforated to admit the passage of cartridges from themagazine in the breech of r the gun, as described.

3. The combination of the feed-regulator T and tumbler D, as and for thepurpose described.

4. The pushing or loading device, consisting Witnesses HENRY L. BEAN, A.F. TIFFANY.
